I suggest to use the dedicated MATCH argument for `org-map-entries':

  (defun as/delete-ignored-heading (backend)
      "Remove every headline with a tag `ignoreheading' in the
    current buffer. BACKEND is the export back-end being used, as
    a symbol."
      (org-map-entries
       (lambda () (delete-region (point) (progn (forward-line) (point))))
       "+ignoreheading"))

I don't think so. Though, after a quick test, I'm unable to reproduce
it. Do you have an ECM?
